PURPOSE:To eliminate trouble to copying operation due to a too short time and to make a contribution to labor-saving operation by setting the time up to automatic shut-off operation optionally within a specific-value range. CONSTITUTION:An input automatic shut-off time can be re-set within three minutes after an electric power source is thrown in. A copy quantity display device 53 displays ''1'' three minutes later and then while copy condition can be inputted, copying operation is allowed a specific wait time later. When the shut- off time is counted, a high-level signal is oututted from the terminal 1 of the output port C of a microcomputer Q1 and a switch SW1 is turned off to shut off the driving power source. Thus, a value which is not within the specific range is also accepted, so the trouble that the contribution to the labor-saving operation originating from that the time becomes too long and trouble to the copying operation due to a too short time are eliminated. |
